Part identifier Jumper type Description Reference section
JP67 1x2 pin header Target MCU pin PIO1_15 I/O enable jumper:
• Open (default setting): Target MCU pin
PIO1_15 input/output is disabled
• Shorted: Target MCU pin PIO1_15 sends/
receives serial data to/from octal flash
memory / external flash memory
JP68 1x2 pin header Target MCU pin PIO0_19 output enable jumper:
• Open (default setting): Target MCU pin
PIO0_19 output is disabled
• Shorted: Target MCU pin PIO0_19 provides
serial clock input to octal flash memory /
external flash memory
JP69 1x2 pin header Target MCU pin PIO0_4 I/O enable jumper:
• Open (default setting): Target MCU pin
PIO0_4 input/output is disabled
• Shorted: Target MCU pin PIO0_4 sends/
receives serial data to/from octal flash
memory / external flash memory
JP70 1x3 pin header External flash connector voltage selection
jumper:
• Pins 1-2 shorted: External flash connector is
powered by VCC_3V3_1V9 supply
• Pins 2-3 shorted (default setting): External
flash connector is powered by VCC_1V9
supply
JP38 (DNP) 1x2 pin header External flash memory reset jumper. External
flash connector and jumper JP38 are not
populated on the board.
JP58 1x2 pin header I3C master pullup resistor control enable
jumper:
• Open: Pullup resistor control is disabled for
I3C master (target MCU)
• Shorted (default setting): Pullup resistor
control is enabled for I3C master
Section 2.13.1
JP25 1x2 pin header MCU-Link target (LPC55S69) force ISP mode
jumper:
• Open (default setting): MCU-Link follows
normal boot sequence (MCU-Link boots
from internal flash if a boot image is found).
With the internal flash erased, the MCU-Link
normal boot sequence falls through to ISP
boot mode.
• Shorted: MCU-Link is forced to ISP mode
(USB1). Use this setting to reprogram the
MCU-Link internal flash with a new image or
use the MCUXpresso IDE with CMSIS-DAP
protocol.
Note: By default, MCU-Link flash is
preprogrammed with a version of CMSIS-DAP
firmware.
